My friends motherinlaw recently had some bathroom taps changed. They isolated the cold feed to the hot water cylinder and turned off the incomming cold main. She is telling my mate that the hot runs ok for a small period of time then trickles out to basically nothing. I think there is a air lock on the feed from the cylinder to the hot water taps, would this sound plausable?. if so its just a case of bridging the cold/hot water taps and forcing some main pressure up the hot water. I am unsure of what system she has cos my mate doesnt know these things so it could be a Yplan or S plan.
What do you guys think?
